At The Bullpen, there are many benefits to our membership program. Bullpen Memberships award you with discounts on lessons, camps and clinics, cage rentals and more.​One of the biggest benefits to being a member is being able to use a batting cage for FREE everyday. Not only does this provide players with the reps they need to improve, but it is also the perfect way to warm up before your next hitting, fieldng or pitching lesson.
